The above is just an example.  I'm not sure what the best solution is but
possibly '-Werror' needs to be disabled when a declaration for a function
needs to be provided.  The prototype for malloc as written above will generate
an warning on a system that lacks a malloc prototype.  I hit this trying
to build a recent version of binutils on vax-dec-ultrix last month.
